TOBACCO-PIPE.

SPECIFICATION forming part of Letters Patent No. 522,777, dated July 10, 1894. Application tiled April 11, 1894. Serial No. 507,155- (No model.)

To all whom it may concern.-

Be it known that I, EDWIN BARRON, a subject of the Queen of Great Britain, residing at London, England, have invented new and use- -ful Improvements in Pipes for Smoking Tobacco, of which the following is a specification.

This invention is an improvement in tobacco pipes andconsists in thenovel features hereinafter described reference being had to the accompanying drawings which illustrate one form in which I have contemplated embodying my invention and said invention is fully disclosed in the following description and claim.

In the said drawings, Figure l is a longitudinal section of a pipe constructed according to my invention, and Figs. 2 and 3 are sections on the lines 2--2 and 3-3 respectively of Fig. 1. Fig. 4 is a plan view of the mouthpiece detached.

a is the bowl of the pipe, b is the stem, and c is the mouth-piece, all of which parts may be of any suitable shape or construction.

The stem bis bored of uniform diameter throughout its whole length and the mouth-.

three grooves indicated by the letters e, e, e all of which terminate at some little distance from the ends of the shank at.

As shown in Figs. 2 and 4 the grooves e, e are placed in communication through a notch f and the grooves e e are placed in communication through a notch 9, while the groove e communicates with the bore of the mouthpiece through a recess 71.. By this arrange passing from the bowl to the mouth-piece will have to pass three times through the length ment it will be obvious that the smoke in of the stem, viz: first along the stem through travel several times through the stem it becomes cooled aud a considerable portion of the moisture and nicotine is deposited thereby preventing them from entering the mouth of the smoker.

It will be readily seen that the mouth-piece and shank can be instantly removed from the pipe and the grooves of the shank can be cleansed of moisture and nicotine. This is a very desirable construction as the passages formed by the grooves in the shank would soon become foul and must be cleaned and by my construction the user is enabled to do this without difficulty or annoyance by simply drawing out the mouth-piece and shank.

What I claim, and desire to secure by Letters Patent, is

In a tobacco pipe, the combination with the bowl having a hollow tubular stem, of a detachable mouth piece provided with a shank adapted to [it within said stem, said shank having a series of longitudinal grooves terminating a short distance from the ends of the stem engaging portions of said shank, one of said grooves communicating by a recess with the pipe bowl, another of said grooves com municating with said mouth-pieceand the other groove or grooves communicating with the firstmentioned grooves at opposite ends of the stem whereby said shank can be re moved from the stem for cleaning, substantially as described.

ED \VIN BARRON.
